Statistical Properties of Thompson's Group and Random Pseudo Manifolds
… multiplication by a generator. We describe a computer algorithm which produces Fordham's Table, and discuss using the computer algorithm to find a corresponding Fordham's Table for different generating sets for F. We expound upon the work of Cleary and Taback by completely classifying dead end …

Optimisation of computed radiography chest imaging utilising a novel simulation technique derived from real patient computed tomography data sets
… a digitally reconstructed radiograph (DRR) computer algorithm that utilises real patient computed tomography (CT) data sets is presented. The algorithm uses a ray casting DRR calculation method to project X-ray pencil beams through CT data and derive the photon energy absorbed in a virtual …

Computerized cardiac mapping system.
This thesis presents the results of the work on a computerized cardiac mapping system for recording simultaneously the signals from three electrodes placed at different sites on the heart in order to diagnose the sites causing arrhythmias. The signals are buffered, amplified, filtered and …

The longitudinal dynamics of a rigid aircraft including unsteady aerodynamic effects
… dynamic system, a carefully derived theory and a computer algorithm have been presented and used. It is our main purpose that a suitable unsteady aerodynamic transfer function be obtained and be coupled to the aircraft quasi-steady dynamic system. A new modified model which includes the unsteady …

Identification and Characterization of A Zebrafish Glutathione S-Transferase Pi
… encoding fifteen zebrafish GSTs. Using a computer algorithm available at the Genebee website, a dendrogram of the fifteen zebrafish GSTs was generated. A zebrafish GST Pi was subsequently cloned, expressed, and purified. An enzymatic assay for purified GST Pi was established using …

Functional requirements to shape generation in CAD
An outstanding issue in computer-aided design (CAD) is the creation of geometric shapes from the description of functional requirements (FRs). This thesis presents a method that can generate assembled shapes from the given FRs without human intervention. To achieve this goal, the design process …

Energy management of three-dimensional minimum-time intercept
A real-time computer algorithm to control and optimize aircraft flight profiles is described and applied to a three-dimensional minimum-time intercept mission. The proposed scheme has roots in two well-known techniques: singular perturbations and neighboring-optimal guidance. Use of …
